The long term effectiveness and tolerance of terguride, a new ergot derivative, as initial therapy were evaluated in 20 patients with pathological hyperprolactinemia (PHP; group A) and 7 patients with acromegaly. We also studied 10 patients with PHP whose treatment was changed from bromocriptine or lisuride to terguride (group B). Terguride, given for at least 6 months in divided doses ranging from 0.25-1.50 mg/day to group A patients, resulted in normal (11 patients) or markedly reduced plasma PRL levels. Gonadal function was restored in all but 2 patients in this group, and the tumors shrank in 3 of 5 patients with a macroprolactinoma and in 1 of 3 patients with a microprolactinoma. In group B patients, positive effects of the previous treatment on PRL levels, gonadal function, and tumor growth were maintained by terguride. Terguride suppressed plasma GH levels below 50% of baseline in 4 of the 7 acromegalic patients. Two of the 27 patients initially treated with terguride complained of mild nausea and postural hypotension only after the first dose (0.25 mg) of the drug. No patient in group B had any side-effects during terguride, with the exception of 1 patient who was also intolerant to bromocriptine. We conclude that terguride is an effective well tolerated dopaminergic agent in PHP.
